The company makes a huge selection of low-end racquets, either aluminum or aluminum and graphite. I'm not sure why any manufacturer would need to offer so many. http://www.qiangli.com/en/prolist.asp?job=plist&protype=1
I played today with one. It was $50 with shipping. I don't remember the model number, only that it began with 5. It was an all-graphite racquet. I was able to generate good racket speed. My service return for short serves was the best yet. Serving was a challenge, though, especially short serves. The racquet was rather light, but not too light, and probably medium flex. Isometric head. The string was factory. Overall, it's a good racquet. It's more powerful than the 2U Carbonex 20 MP, but had more vibration.
